概要 | The reaction of dehydrated castor oil (DCO) and 1,1'-(methylenedi-4,1-phenylene)bismaleimide (BMI) in DMI and subsequent precipitation gave DCO/BMI prepolymer, which was cured at 200 degree C gave DCO/BMI cured product. The FE-SEM analysis revealed that the cured products with C=C ratio 2/1 and 1/1 are homogeneous, while phase separation occurs for the 1/2 product. The Tg, 5% weight loss temperature and tensile modulus of the cured DCO/BMI increased with increasing BMI content. The cured DCO/BMI 1/1 showed the highest tensile strength. The model reaction products of DCO and N-phenylmaleimide (PMI) in DMI were analyzed by 1H-NMR spectroscopy. The 1H-NMR data of DCO revealed that DCO has ca. 4.8 CH=CH bonds per triglyceride and that the ratio of conjugated and non-conjugated diene moieties is ca. 41/59. The NMR data of the reaction products of DCO/PMI at 200 degree C revealed that both Diels-Alder and ene reactions occurs in addition to radical polymerization. |
